Process. Ore, limestone and carbon in the form of coke are put into the top of the blast furnace in layers.At the same time, hot air called "wind" is blown inside the furnace. Special nozzles called "tuyeres" are used to put the air in the furnace. The nozzles are at the bottom of the furnace. This process is called "blasting". It is why it is called a "blast furnace".

LIMESTONE MINING Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.

Limestone: Rock Uses, Formation, Composition, Pictures

Extraction Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made.

Limestone - Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

Is a limestone an ore -

Iron ore is not normally smelted, instead it is reduced in a blast furnace with a mixture of coke & limestone. The coke burns removing the oxygen from the iron ore and melting the resulting iron.

Iron Ore Smelting Process - Brighthub Engineering

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being ...

Deposition of Ores in Limestone

Many contributory causes have in all probability cooperated in the deposition of the ore, such as decrease of pressure and reduction in the temperature of the solutions, the mingling of mineral-bearing waters of different chemical composition entering the limestone formation through distinct fissured belts, etc.; but the important factor ...

Calcination - Wikipedia

In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r = 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.
